Facts About Breathing • You take a breath about 20,000 times a day (~ 12 breaths per minute) • We breath about 500 ml/breath • We breath 10,000 liters or 2500 gallons/day • We breath in over a billion small particles a day (1,000,000,000)
Sources of Air Pollution • Exhaust from Motor Vehicles • Emissions from Chemical Factories • Non-Chemical Industries • Waste Re-cycling • Smoking • Amount of pollution in steadily increasing every minute of every day
Pollutants • sulfur dioxide • nitrogen dioxide • nitric oxide • carbon monoxide • particulates • photochemical oxidants • ozone • toxic metals
Air Pollution Respiratory Health Effects • Short Term • Cough • Shortness of breath • Wheezing • Acute Bronchitis • Reversible reductions in lung function
Air Pollution Respiratory Health Effects • Long-term • Asthma • Chronic Bronchitis • Irreversible reductions in lung function • Emphysema • Increased susceptibility to infection
